Blood Types and Compatibility Concepts

The video tutorial explains the ABO and Rh blood grouping systems, detailing the presence of A, B, and Rh antigens on red blood cells. It covers the compatibility of different blood types for transfusions and highlights the special case of Rh incompatibility during pregnancy, which can lead to complications. The tutorial also guides viewers on creating a blood type compatibility table, emphasizing the roles of universal donors and recipients.

What determines the blood type of an individual?

• The presence of white blood cells

• The amount of hemoglobin in the blood

• The presence of A and B antigens on red blood cells

• The size of red blood cells

What is the Rh factor named after?

• The rhesus monkeys used in experiments

• A scientist who discovered it

• A type of red blood cell

• The region where it was discovered

Which blood type can safely receive Rh-negative blood?

• Neither Rh-positive nor Rh-negative individuals

• Both Rh-positive and Rh-negative individuals

• Only Rh-positive individuals

• Only Rh-negative individuals

What happens if Rh-positive blood is given to an Rh-negative person?

• The recipient's blood will not react

• Nothing, they are compatible

• The recipient will develop immunity to the Rh antigen

• The recipient's body will produce antibodies against the Rh antigen

What condition can occur if an Rh-negative mother has an Rh-positive child?

• Erythroblastosis fetalis

• Hemophilia

• Thalassemia

• Sickle cell anemia

How can erythroblastosis fetalis be prevented?

• By injecting antibodies to destroy the mother's anti-Rh antibodies

• By giving the mother a vaccine

• By changing the mother's blood type

• By ensuring the father is Rh-negative

Which blood type is considered the universal donor?

• AB positive

• O positive

• O negative

• A negative

Which blood type is considered the universal recipient?

• AB positive

• O positive

• A negative

• B negative

What must be considered when determining blood donation compatibility?

• Only the A and B antigens

• The donor's blood pressure

• Both the A/B antigens and the Rh factor

• Only the Rh factor

Why is O negative blood considered universally compatible for donation?

• It has only the Rh antigen

• It has only the A antigen

• It has no antigens

• It has all antigens
